Analog Devices has developed the first Single-pair Power over Ethernet (SPoE) Power Sourcing Equipment (PSE) and Power Device (PD) up to 1km for smart factory and building automation.

The  LTC4296-1 and LTC9111 endpoints provide power and data to devices, even in remote, difficult to access endpoint locations and enables real-time power management and telemetry with low standby power consumption.

Combined with the Chronous ADIN1100 and ADIN1110 10BASE-T1L single pair Industrial Ethernet chips delivers power and data over one kilometre, a significant increase from previous Ethernet standards.

The LTC4296-1 is a 5-port SPoE PSE end point with Classification while the LTC9111 SPoE PD adds Polarity Correction. These support both the SPoE and Power over Data Line (PoDL) variants of single-pair connections up to 52W. Both products are 802.3cg compliant and support Serial Communication Classification Protocol (SCCP).

“The Intelligent Edge is one of the most exciting developments of the digital era as computing power is pushed to previously inaccessible applications and locations,” said Leo McHugh, Vice President of Industrial Automation at Analog Devices. “Analog Devices is committed to delivering the unrivalled technology and solutions our customers need to leverage the full potential of the Intelligent Edge in smart buildings and factories as well as many more applications in the future.”;
